JOURNAL LUBRICATOR.

Application filed September 20, 1921.

T 0 all whom, it may concern:

Be it known. that 1, JAMES J. HENNnssY, a citizen of the United States, residing at New York city, New York, have invented a certain new and useful Improvement in Journal Lubricators, of which the following is a full, clear, and exact description, such as will enable others skilled in the art to which it appertains to make and. use the same, reference being had to the accompanying drawings, forming part of this specification.

My invention relates to journal lubricators such as are used on railway rolling stock, and consists in an improved lubricant receptacle and lubricant pumping mechanism.

The object of my invention is to provide a cam operated pump which will be simple and effective and occupy a minimum amount of space on the car or locomotive journal.

An addition a]. object of my invention is to provide means for preventing the splashing of free lubricant from the lubricator well to the exterior of the lubric-ator.

In the accompanying drawings, illustrating a selected embodiment of my invention Figure 1 is a longitudinal section through my lubricator shown in assembly with the journal and wheel hub oil a railway car.

Fi g. 2 is a transverse section through my lubricator taken on line 22 of Fig. 1.

Fig. 3 is a detail section on line 33 of Fig. 1

The lubricator comprises a reservoir 1 which extends a substantial distance below the journal A with which it is assembled, and the lower portion of which forms a lubricant well 2. The bottom wall of the reservoir has an integral pump cylinder 3 provided with check valves 4 and 5. A pump plunger 6 is slidaloly mounted in cylinder 3 and a horizontal plunger operating rod 7 is slidably mounted in the reservoir and extends exteriorly thereof through the side wall of the reservoir. Plunger 6 and rod 7 are connected through a lever 8 which is pivoted to the reservoir at 9.

Specification of Letters Patent.

Patented July 25, 1922.

Serial No. 501,867.

Positive driving means for the operating rod 7 is supplied by the rotating journal through a collar 10 which may be clamped on the journal as shown and which is provided with a cam surface 11 having a short rise 12 adapted to contact with the outer end of rod 7 upon each revolution of the journal. The inner end of rod 7 is engaged by a compression spring 13 which thrusts the rod outwardly whenever the latter is released by rotation of collar 10.

The reciprocating action of rod 7 reciprocates plunger 6 and alternately draws the lubricant into the pump cylinder 3 through valve 5 and discharges it upwardly therefrom through valve 4:. Each of the walls of the reservoir are offset, as shown, to "Form a seat for a waste pan let, the walls of which are ofifset correspondingly. This seating of the waste pan in the reservoir prevents any splashing of the lubricant from the well to the outside of the reservoir.

The bottom of the waste pan is recessed at 15 to accommodate the pump cylinder and the operating mechanism.

I contemplate the usual modifications of my lubricator. without departing from the spirit of the invention. as set forth in the following claim.

I claim:

In combination. a railway car journal, a journal lubricator including a waste receptacle held in contact with said journal, a lubricant reservoir adjacent to said receptacle, a pump for feeding lubricant from said reservoir to waste in said receptacle, a pump actuating rod extending parallel with said journal exteriorly of said reservoirand receptacle, a cam mounted on said journal and-contacting with said rod to move the latter axially in one direction with each revolution of the journal, and means energized by such movement to return said rod to its original position.

In testimony whereof I hereunto affix my signature this 29th day of June, 1921.

JAMES J. HENNESSY.
